My plant doesn't look so good whats wrong??

[Shosho1]

My two plants dont look so good, i posted one pic in my album of what the leaves are doing. The tops look almost lime gree now not a nice green and some of the fan leaves and the leaves the top leaves look like it has rusty brown splotchs.
and some leaves are yellowing.
The plant is currently in soil and under a 90W LED UFO.
Temp is 65-75 with excellent ventalation and using C02 tablets every other day.
I just ordered a real light.(HPS)
Plant is in 6th week of flowering and I have been feeding big bu (diluted) with water and mollasses since budding started.
From what I have read in Marijuana Horticulture it seems that I have a Magnassium defiency.
I plan on letting it grow for another 4-5 weeks, the trichomes are clear mostly.
The Cheese is supposed to be harvested once they are more amber.
should I use epsom salt diluted with water.
Any advise would be great, I am new to this and planning on going to hydroponic soon.

Well...

Sound very similar to the same probs I was having, not exact though.

Turns out my pH was screwy and it was causing a nutrient defficiency. Mine was most likely a Phosphorus def though, kinda hard to say cause my girls are looking way better now but I'm still not all the way outta the woods just yet.

I had to up my Phos and get my pH back under control. pH, IMO is prob gonna be your best bet to get back into shape.

Some of the vets should chime in when they have time, wait to see what they say to be sure though.

BTW, I believe a 18/6 light cycle is best for auto-flowers but I believe it might vary by the strain. Some quick google search and a lot of comments saying 12/12 will diminish your yeild and stress some auto's...

"not sure i lost my PH meter"


Howzit, brah?
That poor thing looks PHucked to me.
Suggest you find, borrow, or buy a PH reader ASAP.
Measure the run-off.
Adjust your input, gently, as needed.
Watch the new growth for results.
The old fan leaves will not recover.

Aloha and good luck

Auto flowers in clone? that one pic of the leaf kinda looks like mg deficiency, usually caused by nut lock out. try flushing; if you tried that, then add a small amount of a mag supplement, cal/mag (botanicare) is usually what everyone uses, gives a dose of mag and cal, but usually nut lock out is what is happing cause you got nice new soil and stuff. Flush with allot of water if you have a 3 gallon pot I suggest using 6-9 gallons of clean phed water to flush and if you have a flushing agent use the recommended doses for that in the flush.
